Authorities tracked down and arrested a man accused of whacking another man across the head with a skateboard during a dispute earlier this week at Tom McCall Waterfront Park.

Ronald Tucker, 42, was taken into custody hours after the attack when he was spotted parked in a truck across the river near the Eastbank Esplande, the Portland Police Bureau reported. He was accused of second-degree assault and booked into the Multnomah County jail.
